Students learn the concept of elapsed time and how to determine it with the help of a ruler. What is Elapsed Time? You have to go to a party at 8 pm and you are supposed to go shopping with your best friend at 6 pm. But before you go for shopping you need to clean your room, do laundry and dishes. Now, will you plan how to manage these things within the given time? Or will you start getting things done, unplanned, wising that you do it all in time? The amount of time from the start of an event to its end is known as Elapsed time. To be more precise, the elapsed time can be defined as the time from one time (6 pm) to another time (8 pm) A clock is an essential tool when it comes to measuring time.
